Our storage heating currently has a single control thats marked min-max.
This links up to an outside temperature probe and then by reference to the manual it shows what percentage of power is put through the floor heating during the off peak power hours. Eg no matter the setting you get 100% of power if its below 3C, at 8C you'd get no heating at min, circa 50% at the mid point and 100% at max.
We now have a new controller thats waiting installation which not only has the min-max controller but has a number of hours (1-7). One obvious advantage would be to cap the power useage at below 3C as you'll still get 100% but could now limit it to a shorter time than the full 7 hours of off peak.
So we effectively currently have it at the mid point and 7 hours so at 8C would get half power for full time but we could once the controller is change alter that to full power for half time. In my uneducated mind this should cost the same but mean we get too little heat when its very cold and continue to get a bit of heat when its actually mild. Would there be any other advantage of full power/half time -v- half power/full time?
